PENINSULAR PRONGHORN
Some wild pronghorn have shown marked recovery
with protection, but this subspecies remains at the edge.
Existing only on the Baja California Sur peninsula, fewer
than a hundred wild peninsular pronghorn survive, along
with a herd of captive animals used to help bolster the
wild population. The ungulates are adapted to desert
conditions, but further warming and reduced rainfall
will affect both their winter and summer forage.

BULL TROUT
It’s a cold-water fish in a warming world whose
Rocky Mountain habitat could decline by 50 percent
within 70 years, biologists say. But even if warming
is extreme, some high-elevation headwater streams
should remain chilly enough to support resilient popula-
tions and resist invasions by competitors. Ensuring the
protection and connectivity of spawning and rearing
streams is crucial for migration.
